Independent variable (x): hours

Dependent variable (y): dollars

Proportional relationship: y = 3.50x

What is the Equation of a Proportional Relationship?

Given a proportional relationship between an independent variable (x) and a dependent variable (y), and m is the unit rate or slope, the equation for the relationship is expressed as: y = mx.

In the graph given, we have the following:

  • Independent variable (x): hours
  • Dependent variable (y): dollars

Using, a point (1, 3.5):

m = y/x = 3.5/1

m = 3.5

Plug in the value of m into y = mx to get the equation that represents the relationship:

y = 3.50 x

Therefore, we can conclude that:

Independent variable (x): hours

Dependent variable (y): dollars

Proportional relationship: y = 3.50x
